Background: Homeless population has been severely affected by the COVID-19 pandemic. Their living conditions, comorbidity with different pathologies and a greater frequency of mental disorders, make this population vulnerable. Method: We implemented a program of serial visits in a hostel for confined homeless of the city council social services, for the monitoring and treatment of mental disorders and substance abuse problems. Accompanied by serial phone and email contacts. Results: A highly significant percentage (63%) had mental disorders or substance abuse, requiring pharmacological intervention, and 37% began follow-up in resources of the Mental Health and Addiction network of the Psychiatric Service at the end of the program. Hospital emergency service visits were drastically reduced. None of them were infected with COVID-19. An individualized Social plan was drawn up in order to reintegrate them with support in the community. Conclusions: The Results have been really positive, meeting all the objectives and opening up developing new programs in the future, in the pandemic outbreak and out of it.
In the present study the prognostic value of both DNA ploidy and the proliferative activity of tomour cells were studied in a series of 76 consecutive patients suffering from gastric tumours. DNA ploidy and the proliferative index (as measured by the percentage of S-phase cells) were determined by flow cytometry using fresh tumour specimens.The presence of DNA aneuploid clones by flow cytometry was detected in 62% of the cases (mean DNA index of 1.63 ± 0.46; range 1.08–2.92), the mean proportion of S-phase cells being of 18.4 ± 11.5%. In comparison with diploid cases, aneuploid tumours showed a higher proliferative activity (cases with more than 15% S-phase cells: 18.4% versus 6.1%, p = 0.0001) as well as a higher incidence of node involvement (95% versus 68%, p = 0.001). By contrast, no significant differences were detected with respect to sex, age, histologic grade and type, clinical stage, tumour size and the incidence of extranodal involvement.Upon grouping the patients according to the proportion of S-phase cells no significant differences were observed for the clinical and biological parameters explored except for an association between a high percentage of S-phase cells and the presence of DNA aneuploidy (40% versus 96%, p = 0.0001). Regarding survival the presence of DNA aneuploidy was significantly associated with poor outcome as compared to the diploid cases (median of 15 versus 26 months, p = 0.005). By contrast, the proportion of S-phase cells did not predict patients’s outcome.Multivariate analysis of prognostic factors showed that the presence of DNA aneuploidy (p = 0.003) together with the histologic type (p = 0.03) and the existence of extranodal metastases (p = 0.05) were the best combination of prognostic factors for survival prediction.
We investigated whether there was an increased interest in quitting smoking in late February, March, and April compared with the preceding weeks. The interest in the search term 'how to quit smoking' showed significant increase on 9 March (90 RSV) and the interest in the search term reached 100 RSV on 19 April (Fig. 1). The interest in the search term 'how to quit alcohol' showed significant increase on 11 February (100 RSV). However, the interest for both the search terms was not stable over the study period (Fig. 1). Our study results showed no consistent increase in the number of searches for quitting smoking or quitting alcohol on Google during the study period (February to May). A recent study analyzing Google Trends regarding smoking cessation searches worldwide during the early months of the COVID-19 outbreak (9 January 2020 and 6 April 2020) also failed to show a tendency for increased interest in any of the key terms related to smoking cessation ('quit smoking,' 'smoking cessation,' 'help quit smoking,' and 'nicotine gum'). 8 However, another study from the Netherlands showed a significant increase in RSV 1 to 4 weeks after the introduction of the smoking ban in restaurants and bars in 2008, and also after the introduction of smoking cessation support in 2011. 10 Our study results may indicate that there has been no significant increased interest in quitting smoking and alcohol, at least among the Indian population who use online resources for health-related information. Our results further highlight the need for continuing public health efforts to inform the Indian public regarding the negative effects of smoking and alcohol during the COVID-19 pandemic. However, our study results were preliminary, and further research is needed to determine the long-term trend and compare it to the results of other studies.
Cervical cancer and its precursors low-grade squamous intraepithelial lesions (LSIL) and high-grade squamous intraepithelial lesions (HSIL) are associated with infection by human papillomavirus (HPV), in particular HPV 16 and 18. The distribution of the HPV genotype varies with the severity of cervical disease, age and the geographic location of the patients. We report the results of a population study carried out in a region of north-western (NW) Spain aimed at determining the prevalence of single and multiple infections by 35 types of HPV using low-density microarrays for 113 cases with negative for intraepithelial lesions or malignancies; 588 with atypical squamous cells of undetermined significance (ASCUS)/LSIL; 183 with HSIL; and seven cases of squamous cell carcinomas. Of the 891 patients analysed, 50.2% had single infections and 49.8% had multiple HPV infections. In women aged below 30 years, there was a predominance of multiple infections (p = 0.027). ASCUS/LSIL was associated with multiple and HSIL with single infections (p = 0.025). We observed significant increases in the percentage of infections due to a high-risk (HR) type of HPV when the severity of the cytological lesion increased (p = 0.001). No relationship was found between greater aggressiveness in the cytological diagnosis and a higher number of HPV types involved in multiple infections. The five most frequent genotypes were HPV 16 (26.3%), 53 (18.2%), 51 (17.3%), 6 (14.8%) and 66 (13.1%). The prevalence of HPV 16, 33 and 58 increased significantly from ACUS/LSIL to HSIL and the prevalence of HPV 51, 53 and 66 decreased. HPV 16 was the only genotype that showed a significant increase in prevalence when the severity of the cytological disease increased in single infections (p = 0.0001). The implementation of bivalent prophylactic vaccination could potentially lead to prevention in 32% of the population included in the study - in at least a quarter of patients with ACUS/LSIL (26.7%), and in half of HSIL (50.2%).
Elastofibroma is a rare, benign fibrous proliferation that most commonly occur in periscapular soft tissues and is characterized by accumulated elastic fibers. Although the lesion is generally regarded as a reactive process, an unusual fibroblastic pseudotumor or as a fibroelastic tumor-like lesion, its etiology remains unknown. Cytogenetic studies in these lesions detected chromosomal instability and some recurrent clonal chromosomal changes, which raised the possibility that the lesion represents a neoplastic process. Here, we report the genomic alterations detected by array-based comparative genomic hybridization (aCGH) and by multiplex ligation-dependent probe amplification (MLPA) in two cases of elastofibroma. Both cases showed losses on 1p, 13q, 19p, and 22q by aCGH. In addition, deletion of CASR (3q21), GSTP1 (11q13), BRCA2 (13q12) and gains on APC (5q21) and PAH (12q23) were observed by MLPA in both samples. Genomic screening studies of this fibrous proliferation may lead to identify chromosomal regions containing genes involved in the development of elastofibromas.
The present work reports on the findings obtained by fine-needle aspiration of two pilomatrixomas located on the upper limbs whose diagnosis was confirmed histologically. In both cases, the cytology disclosed a proliferation of small round basaloid cells that were dispersed and grouped in clusters together with squamous cells and abundant multinucleate giant cells. The differential diagnosis with other neoplasms is discussed.
